Bypass paywalls for scientific documents

Bypass paywalls for scientific documents by downloading them from sci-hub instead of paying something like 50 bucks for each paper. This script adds download buttons on Google Scholar, Scopus and Web Of Science, which lead to sci-hub.tw. In this way you can get free access to scientific papers even if you (or your university) can't afford their prices.

  • v3.4.3 06-07-2022

    [FIX] Fixed the domain updater so that it now correctly recognizes the real sci-hub website as original.
    [ADDED] Styling in the console log for the domain updater, so that it's easier to see how the script checks sci-hub's current domain.

  • v3.4.2 02-11-2021

    Released under AGPL 3.0 license.

  • v3.4.2 04-10-2021

    In order to make the script ready for sudden Sci-hub's domain changes without intervention, I've introduced an auto-update function that retrieves the new domain from the officila VKontakte page of Sci-hub project. To be able to update, the script needs the permission to connect to vk.com: once a day, the script checks if Sci-Hub can be reached at the known domain and if it can't be reached, the script retrieves the new domain (if it's been updated) from Sci-Hub's official VK account.
    I hope it works as expected! I've mainly tested the autoupdate feature on GreaseMonkey for the moment, but even if it's not working on your browser/userscript manager, the script will fall back to the default domain (currently sci-hub.ru).
    On Tampermonkey you will be asked to confirm the access to a new domain everytime Sci-Hub's domain changes.

    I hope it works as expected: you should see an alert on the first time you use this updated version of the script and any other time the domain changes.
